Question

Enzymes are basically

• A. Sugars
• B. Proteins
• C. Fats
• D. Vitamins

Answer 1

The correct option is B Proteins

All enzymes are chemically proteins. They are made up of a chain of amino acids and are special proteins which are responsible for various reactions in the body and do not increase the body temperature. They are specific in their action and particular enzyme acts on a single substrate. They can either breakdown bigger molecules into smaller ones as in digestion or build up larger molecules from smaller ones as in assimilation of body parts form raw materials. Certain enzymes require the presence of other substances known as cofactors for their action. Such an entire active enzyme is called a holoenzyme which is made up of two parts- protein part known as apoenzyme and non- protein part called co-factor which can be a coenzyme, prosthetic group or metallic ion activator.

Thus, the correct answer is option B.
